Question 1

A retail company is using an Order API to accept new orders. The Order API uses a JMS queue to submit orders to a backend order management service. The normal load for orders is being handled using two (2) CloudHub workers, each configured with 0.2 vCore. The CPU load of each CloudHub worker normally runs well below 70%. However, several times during the year the Order API gets four times (4x) the average number of orders. This causes the CloudHub worker CPU load to exceed 90% and the order submission time to exceed 30 seconds. The cause, however, is NOT the backend order management service, which still responds fast enough to meet the response SLA for the Order API. What is the MOST resource-efficient way to configure the Mule application's CloudHub deployment to help the company cope with this performance challenge?

A : Permanently increase the size of each of the two (2) CloudHub workers by at least four times (4x) to one (1) vCore

B : Use a vertical CloudHub autoscaling policy that triggers on CPU utilization greater than 70%

C : Permanently increase the number of CloudHub workers by four times (4x) to eight (8) CloudHub workers

D : Use a horizontal CloudHub autoscaling policy that triggers on CPU utilization greater than 70%

Answer: D

Question 2

What is true about API implementations when dealing with legal regulations that require all data processing to be performed within a certain jurisdiction (such as in the USA or the EU)?

A : They must avoid using the Object Store as it depends on services deployed ONLY to the US East region

B : They must use a Jurisdiction-local external messaging system such as Active MQ rather than Anypoint MQ

C : They must te deployed to Anypoint Platform runtime planes that are managed by Anypoint Platform control planes, with both planes in the same Jurisdiction

D : They must ensure ALL data is encrypted both in transit and at rest

Answer: C

Question 3

Select the correct Owner-Layer combinations from below options

A :

1. App Developers owns and focuses on Experience Layer APIs

2. Central IT owns and focuses on Process Layer APIs

3. LOB IT owns and focuses on System Layer APIs

B :

1. Central IT owns and focuses on Experience Layer APIs

2. LOB IT owns and focuses on Process Layer APIs

3. App Developers owns and focuses on System Layer APIs

C :

1. App Developers owns and focuses on Experience Layer APIs

2. LOB IT owns and focuses on Process Layer APIs

3. Central IT owns and focuses on System Layer APIs

Answer: C

Question 4

Traffic is routed through an API proxy to an API implementation. The API proxy is managed by API Manager and the API implementation is deployed to a CloudHub VPC using Runtime Manager. API policies have been applied to this API. In this deployment scenario, at what point are the API policies enforced on incoming API client requests?

A : At the API proxy

B : At the API implementation

C : At both the API proxy and the API implementation

D : At a MuleSoft-hosted load balancer

Answer: A

Question 5

Question 10: Skipped

An API implementation returns three X-RateLimit-* HTTP response headers to a requesting API client. What

type of information do these response headers indicate to the API client?

A : The error codes that result from throttling

B : A correlation ID that should be sent in the next request

C : The HTTP response size

D : The remaining capacity allowed by the API implementation
